SPECIFICATION forming' part'of Letters Patent No. 746,955, dated December 15, 1903. Appiioaitn nea Aprii zt.' 196,1.' sein no. 57,589. un modem To a/ZZ whom t may concern:

Be it known that I, LYMAN O. GOODWIN,

a citizen of the United States, residing at North Andover, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements inValves, of,

This invention relates to improvements in l valves, and particularly to rotary valves.

One object of the invention is to so construct a valve that the exhaust may be delivered from the end of the valve, While the su pply is delivered at a point intermediate the ends. l

Another object is to so construct a valve and its casing that the supply-inlet is constantly open, while the exhaust-ports are alternately opened.

Another object of the invention is to so ccnstruct a valve that the exhaust may be received at the periphery of the valve and delivered at the end thereof, while' the supply is received into that portion of the valve which is intermediate the ends, as well asintermediate the exhausts. Y

Another object of the invention is to provide a novel and simple rotary valve.

This invention consists in a valve havinga series of channels open at the periphery of the valve and at one end thereof.

The invention also consists inla valve-casing having an inlet-port, a pair of outlet-ports considerably less in diameter than the inletport, and a wall intermediate the outlet-ports, together with a valve havinga transverse su pply-channel adapted. to alternately connect the inlet-port with the respective outlet-ports, and a pair of exhaust-channels having openings in the periphery of the valve and adapted to be broughtopposite the corresponding outlet-ports of the casing at times.

The invention also consists in a cylindrical valve having a transverse channeland a series of channels open at the periphery of the valve and at one end thereof.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described, and pointed out in the claim.

Figure 1 represents an elevation of the iniproved valve and the casing therefor. Fig. 2 represents Aa longitudinal sectional View taken on line 2 2, Fig. 3. Fig. 3 representsa 55 vvertical sectional vievir of the same, taken on line 3 3, Fig. 2.

Similar numbers of reference designate corresponding parts thrpughout.

` VIn carrying this invention into practice it 6o has been my main object to provide a rotatable valve whereby a supply might be `alternately directed to a plurality of mechanisms and that such mechanisms might be alternately connected, by channels in the valve, with outlets through which the exhaust duid or gases l rom said mechanisms is free to pass.

In thev drawings, 5 indicates the cylindrical casing, having' the annular lip 6 and furnished With the inlet-port 7 and With the 7c outlet-ports 8 and 9, the wall l0 between these ports 8 and 9 being directly opposite the port 7. `Rotatablymounted inthe casing is the valve 11, having' the stem 12, adapted to receive mechanism for causing the rotation of the valve, and furnished with the transverse .supply-channel 13With its enlarged mouth of the drawings, the valve is in the closed position. When the valve is rotated in the direction indicated by the arrow, the mouth 18 of the channel 16 is gradually brought 85 opposite the port 9 while the inner end of the channel 13 is brought opposite the port S. The gas or fluid may now pass throughv the channel 13 and the port 8 of the casing to the mechanism, While the exhaust from the mech- 9o anism connected with the port 9 may pass through this port into the channel 16 and thence through the open end of said channel' into any suitable receptacle or into the open air. The rotation of the valve being reversed, the month 17 of the channel 15 is brought opposite the port 8 to receive the exhaust from its related mechanism, and the channel 13 is brought opposite the port 9 to deliver a supply of gas or duid to its related mechanism. roo The rocking back and forth of the valve thus. alternately opening the supply to one mechansm while it opens the exhaust to the other mechanism.

Having thus described my invention, I of the valve and openings extending to the lo claim as new and desire to secure by Letters Paten 1;- v

The combination with a. suitable casing, of a cylindrical valve having al transverse port and an exhaust-pori located at; each side of nhe tr'finsverse port, and extending longitudinally of said valve, said exhaust-ports having curved walls forming the peripheral portions end thereof.

In testimony whereof I afx my signature in presence of two witnesses.

LYMAN O. GOODWIN.
